Super-acceleration in non-minimal derivative coupling model

arXiv:1012.5719 · doi:10.1103/PhysRevD.83.107301

Abstract

A scalar field model with non-minimal derivative coupling to gravity is considered. It is shown that although in the absence of matter and potential the phantom divide line crossing is forbidden, but for the power law potential and in the presence of matter this crossing is, in principle, possible.
